Failed to use EVSPIN32G4-dual with MCSDK6.2 to control dual 3-phase BLDC with FOC/Hall

[nexmak]

Hello,

I'd to drive two 3-phase BLDC with FOC & Hall on EVSPIN32G4-dual board, generated the code from MCSDK6.2 (support dual motor control).

First, I control the M1 motor only, it's well, then stop the M1 and control the M2, it's also well.

But when I control the M1 first and then wait for seconds to control the M2, the M1 and M2 both are unstable & vibrating. 

Measure the PWM signal from gate driver STDRIVE101, found the PWM signal is anomaly.

I cannot figure out the reason, is it caused by concurrent FOC or some else? 

Can someone give some advice, thanks.

Hello,

Could you please explain what you mean by "Measure the PWM signal from gate driver STDRIVE101, found the PWM signal is anomaly"?
